HOSE-COUPLING.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed April 10, 1907. Serial N 0. 367,395.

To all whom it may concern:

Be it known that 1, CHARLES F. BROWNE, a citizen of the United States,residing at the city of Washington, in the District of Columbia, haveinvented new and useful Improvements in Hose-Couplings, of which theiollowing is a specification.

This invention relates to hose couplings of the type wherein thecoupling members are threaded into the ends of the hose sections, andhas for its objects to provide a comparatively simple, inexpensivedevice of this character in which the cou ling members may be readilyscrewed into t e hose and one in which said members will be securelyfixed against retrograde or unscrewing movement.

With these and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a side elevation of a hosecoupling embody ing the invention. Fig. 2 is a longitudinal sectiontaken centrally through the coupling and showing the same applied foruse. Fig. 3 is a detail cross section taken on the line 33 of Fig. 2.

Referring to the drawings it will be seen that the coupling member whichconnects the hose sections 1 comprises a air of coupling members 2 and 3rovided with screw threaded necks 4 Whic enter the meeting ends of thesections 1 and are in turn connected by a coupling member or nut 5having at one end an inwardly projecting flange 6 adapted for engagementwith a corresponding outwardly projecting flange 7 formed on the end ofthe member 2, the nut 5 being internally threaded as at 8 for detachableengagement with a similarly threaded head 9 formed on the hose engagingmember 3.

The foregoing parts are of the usual or any appropriate form andmaterial and the members 2 and 3 may be connected together in anysuitable manner, otherwise than by the nut 5, the essential featurebeing that the coupling members 2 and 3 be rovided with the screwthreaded portions w 'ch enter and have threaded engagement with theadjacent ends of the hose sections 1.

forward rotation of the members in the operation of engaging them withthe sections 1, while the threads on the portions-4 will as usualprevent the sections 1 from escaping by a relative longitudinal movementof the parts from the members 2 and 3.

It will be observed that while the device is of a simplified nature theteeth 10, which may be inexpensively formed during the course ofmanufacture, serve as an effectual.

means for preventing the coupling members from unscrewing.

What I claim is:

1. In a hose coupling, a tubular coupling member having an externallythreaded portion adapted for screw threaded engagement with a hosesection, and spurs provided on said threaded portion and arranged incircumferential alinement and disposed for engagement with the sectionto prevent retrograde or unscrewing movement of the member.

2. In a hose coupling, a tubular coupling member having an externallythreaded neck adapted for screw threaded engagement with a hose section,and circumferentially disposed rearwardly pitched teeth in peripheralalinement provided on said threaded portion .for engagement with thehose section to prevent retrograde or unscrewing movement of the memberrelative thereto.

In testimony whereof, I affix my signature in presence of two witnesses.

CHARLES F. BROWNE.
